Encode HTML Entities
💡 Secure Your Code
Convert reserved HTML characters into safe entities to prevent rendering issues and Cross-Site Scripting (XSS) vulnerabilities. This tool instantly transforms characters like < and > into their secure counterparts (<, >).
📘 Best Practices
- Stop XSS Attacks Sanitize user-provided data by neutralizing characters that browsers interpret as executable code.
- Display Raw HTML Showcase code snippets on your website without the browser rendering them as actual page elements.
- Reverse the Process Use the unescape function to revert entities back to plain text for quick debugging and inspection.
🧐 FAQs
Named vs. Numeric Entities?
< is a named entity, while < is its numeric equivalent. Both render the same character, but named entities are much easier for developers to read and maintain.
How does this prevent XSS? Cross-Site Scripting (XSS) occurs when attackers inject malicious scripts into your pages. Escaping output is your primary defense, ensuring the browser treats the input as harmless text rather than a script to be executed.
🚀 Pro Tip
While this tool prioritizes the "Big 5" reserved characters (", ', &, <, >), HTML5 actually supports over 2,000 named entities for everything from mathematical symbols to international currency.
